20080236118 | Exhaust particulate filter for a machine engine system and assembly method therefor - An exhaust particulate filter for an engine system includes a housing having an inlet, an outlet and a shell shaped to fit the particulate filter within a predefined spatial envelope. Filter elements arranged in a bundle and having a packing arrangement are positioned within the housing. Each of the filter elements includes a perforated tube wrapped with fibrous metallic filter media. The bundle defines a perimetric line at least partially matched to the shape of the shell. An assembly method for a particulate filter includes arranging filter elements in a packing structure within a bundle, the bundle having peripherally located filter elements and internally located filter elements. The filter elements each include a perforated tube wrapped with fibrous metallic filter media. The assembly method further includes positioning the bundle of filter elements within a housing having a shape at least partially matched to a shape of the bundle. A unique method of joining various of the components via swagging is also disclosed. Clamping of the filter media, and joints between filter element and support plates, may be achieved via swagging, for example. | 10-02-2008 |

20100263353 | EXHAUST TREATMENT DEVICE HAVING FLOW-PROMOTING END CAPS - An end cap for an exhaust treatment device is disclosed. The end cap has a cylindrical housing with an axial direction, a radial direction substantially orthogonal to the axial direction, a first open end, and a second closed end opposing the first open end in the axial direction. The end cap also has an integral port member extending from an annular surface of the cylindrical housing. The integral port member has a central axis aligned in the radial direction, and an exterior surface of the integral port member tangentially connects to an exterior surface of the cylindrical housing. | 10-21-2010 |
20140032046 | TRACK DRIVE SYSTEM AND METHOD - The disclosure may provide a method of driving a mobile machine that includes a left-side track assembly and a right-side track assembly for propelling the machine and an implement for performing work. The method may include determining whether the machine is traveling approximately straight forward or backward, and determining whether a load exerted on the implement is less than a threshold load value. A signal may be output, with a controller, to adjust a speed of the left-side track assembly or a speed of the right-side track assembly when the machine is traveling approximately straight forward or backward and the load exerted on the implement is less than the threshold load value, to thereby bring the left-side track assembly out of phase with the right-side track assembly. | 01-30-2014 |

20090275691 | METHOD FOR THE PRODUCTION OF CO-EXTRUDATES COMPOSED OF POLYSTYRENE AND OF A CROSSLINKED POLYVINYLPYRROLIDONE WITH REDUCED RESIDUAL STYRENE MONOMER CONTENT - A method for removing residual styrene monomers from co-extrudates comprising polystyrene and water-insoluble, crosslinked polyvinylpyrrolidone, which comprises subjecting an aqueous suspension of the particulate solid co-extrudate to a heat treatment at temperatures of 60 to 99° C., the weight ratio of solid co-extrudate to water in the suspension being 1:1.5 to 1:20, and the concentration of the suspension being kept constant during the treatment. | 11-05-2009 |
20090291164 | METHOD FOR REGENERATING AN AUXILIARY FILTERING AGENT - Processes comprising: (i) providing a filter aid comprising a co-extrudate of a water-insoluble polyvinylpyrrolidone and a thermoplastic polymer; (ii) treating the filter aid with aqueous alkali; (iii) subsequently treating the filter aid with an enzyme; and (iv) subsequently thereto carrying out a second treatment with aqueous alkali, to provide a regenerated filter aid, and uses therefor. | 11-26-2009 |
20100176069 | METHOD FOR REGENERATING A FILTER AID - Methods for regenerating filter aids which comprise inorganic, natural or semisynthetic filter aids. The method comprises subjecting the filter aid to a first treatment with an aqueous alkaline solution, treating the filter aid with enzymes, treating the filter aid with a surfactant, and subjecting the filter aid a second treatment with the aqueous alkaline solution. The enzyme treatment and the surfactant treatment steps may be carried out simultaneously or in any order. | 07-15-2010 |

20080202396 | METHODS AND APPARATUSES FOR REMOVING MERCURY-CONTAINING MATERIAL FROM EMISSIONS OF COMBUSTION DEVICES, AND FLUE GAS AND FLYASH RESULTING THEREFROM - A method of removing mercury or mercury-containing material from flue gas produced by a coal-burning main furnace includes feeding coal, which contains mercury or mercury-containing material, to a main furnace which produces flue gas. The method further includes feeding the coal to an auxiliary burner which produces a slipstream of flyash, feeding the slipstream of flyash from the auxiliary burner into the flue gas produced by the main furnace, and introducing a mercury-active oxidant to the coal being fed to the auxiliary burner, the combustion air fed to the auxiliary burner, and/or the flyash. | 08-28-2008 |
20080223270 | METHOD OF USING NANOALLOY ADDITIVES TO REDUCE PLUME OPACITY, SLAGGING, FOULING, CORROSION AND EMISSIONS - A process for improving the operation of combustors includes the steps of burning a carbonaceous fuel in a combustor system and determining combustion conditions within the combustor system that can benefit from a targeted treatment additive, wherein the determinations are made by calculation including computational fluid dynamics and observation The process further includes locating introduction points in the combustor system where introduction of the targeted treatment additive could be accomplished. Based on the previous steps, a treatment regimen for introducing the targeted treatment additive to locations within the combustor system results in one or more benefits selected from the group consisting of reducing the opacity of plume, improving combustion, reducing slag, reducing LOI and/or unburned carbon, reducing corrosion, and improving electrostatic precipitator performance. The targeted treatment additive comprises an alloy represented by the following generic formula (A | 09-18-2008 |
20090071067 | Environmentally-Friendly Additives And Additive Compositions For Solid Fuels - Fuel additive packages and fuel compositions, suitable for use with solid fuels, having environmentally compatible characteristics as defined by European Council Directive 67/548/EEC is disclosed. Such additive packages and compositions may include components selected from non-persistent materials, non-bioaccumulative materials, and/or or non-toxic materials. | 03-19-2009 |
20100300929 | COMPOSITIONS AND METHODS FOR IMPROVING A CATALYTIC REFORMER - The present disclosure relates to a catalytic reformer system, including a feed stream to a catalytic reformer comprising naphtha and at least one manganese-containing compound.

20160108332 | FUEL COMPOSITION AND METHOD OF FORMULATING A FUEL COMPOSITION TO REDUCE REAL-WORLD DRIVING CYCLE PARTICULATE EMISSIONS - In order to blend fuels to meet specific regulatory and industry requirements, for instance octane requirements, different octane blending components can be used. One added component includes a composition of higher aromatics content. Unfortunately, this aromatic content may increase the particulate emissions of an internal combustion engine when the high aromatic fuel is combusted in that engine. As explained herein, reducing the aromatics content and replacing that octane increasing requirement with an alternative octane enhancer results in a formulated fuel that will have lower particulate emissions in the real-world driving of that engine as compared with a fuel having higher aromatic content. | 04-21-2016 |
